I have noticed, with input based patches, that since the original input keeps coming out of USB1 out, I need to send my input based patch to USB2 or 3 and mute USB1.
-- Edit -- More things to try: change vocoder mode from Osc hold to Oscillator. Go to the FX1 tab and play around with the input options. Try static, dynamic, and off again, while the input is coming from your DAW.
but not the voice or the sound from the input
You probably know that, but for other people reading - You are not supposed to hear the input itself, but to hear the source sound (oscillators, noise, or another input) being given the properties of your input, in terms of the balance between spectral components. This way, a synth sound can be given the properties of speech.
What do you hear when you move the source mix slider to both extreme positions? Remember to do this when the Virus track is armed and the audio source that you are routing into the virus is either a pre-recorded track that is playing, or a live input track that is armed.
